pplication filed January 11, 19618. Serial No. 410,461.

To all 'whom it may concern:

lie it lmown,tliat we. Eiixusr l". CioLiA and Louis F. PrLLiz'rinn, a subject of the King.1r of Italy and a citizen of the United 5 States. respectively. rcsidiiiff atNew York,

in the. county of New Yoiil( and State of New York, have invented certain new and useful Improvements in Shock-Absorbers,of which the. following is a full, clear, and

exact.` description, such as will enable others skilled inthe art to which it appertains to make and use the'sanie.

This inventionrelates to the mounting of vehicle bodies. i

5 K One of the objects thereof is to provide simple and effective means for preventing excessive" swaying or bounding of vehicle bodies. Y A

Another object: is to provide means of the above type of durable construction and reliable action.

Other objects will he .in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the q features of constriuztion` coiiibinalious ot' elements and arrangeni it of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated.

0 In the accompanying drawings, wherein are shown one or more of the various possible. embodiments of the several features of this invention, liglfuro 1 is a side elevation; Fig. 2 is a sectional view taken aloner the line az-#m of Fig. 1 and showingF the parts upon a larger scale; Fig. 3 is a side elevation of a slightly1 different. embodiment; Fig. 1 is a sectional vicw tak'en along the line .iv-.r of Fig. 3;' Fig. 5 is a detail edge view -10 of parts shown in Fig. 3. Similar reference characters refer to similar parts throughout'. the several views of the drawings.

lu order that certain features of this in- 4 5 veut ion may be the more readily and fully understood, it may be noted that in connection with apparatus of the general nature of thaty with which this invention deals, if it be attempted to control the action of the springgear by means depending u on frictional engaging surfaces, these sur aces are sub- ]ccted to almost constant wear during the travel of the 'vehicle and are either worn away or polished smooth so as to be of remedy this defect by providing means for tightening the surfaces, there is not only frequent adiustineii'n required, but the hearY The elin'iinatioii ot' objectionable features of this nature is among the dominant ainis of this invention. Y l

Referring now to the accompanying;I drawings, there is shown in Fig. 1 a spring bar or portion of the vehicle frame l upon which is mounted the body, diagranuiiatically indicated at; :21. Connectcdwith the bar l is the spi-ing 3, herein shown as of the 'semi-elliptic type and mounted upon the axle 4. Secured in placeupon spring 3. as by the clips 5, is a saddle t having piiotzilly ,mounted thereon. as at 7. ay link S jointed at its upper end to a swinging ineinher 9. This nieuihcr is'l'irovided upon its inner surface. with sector-shapcd projections l() having inclined bearing surfaces li. Mounted upon the bar 1. as b v means of bolts l2 passing through perforated lugs t3. is a plate 14 havingr formed upon its outer surface the projections 15 similar-iii forni and function to projections 10 and adapted to intcrft with there is a tendency of the body to hound or oscillate with respect to the axle. to a disagreeable degree. the hodviv and axle move toward and away from one another,`

l however, -the link 8 swings the member-9 little practical value. lf it. be attempted to ing members must he replaced when worn.

v'nliout bolt 18, .the cam or inclined meeting surfaces f the projections 10 and 15 cruising this member, uponnswingiiig, to he forced outwardly roiii the plate i4. This inovement is resisted by the spring 1G which is distorted therel'iy 'und upon the edges ofthepro'iectioiis pushing ono another, if the ineinlier is carried to Ithis extent` the spring forces the projections one within; :mother iii :1

Loosely passing through members Z4 and 25 is a heiiiy in 2? the outer ends oli' which are threade and provided with nuts und Washers 29. These nuts .servo to hold in position stur-shaped springs 30 and 3l which force the plates 24 und Q5 toward one another. Upon arms 20 und Q1 :ire formed or mounted the annular i'iungcs 32 und 33 the edges of which reet in Contact :ind serve to :iet as :i dust-guard for thc moving,lr ports. It will he seen that upon the :irms 30 und 21 Aowiiiging with reference one to another, their movement is opposed. b i' the action of :springs 30 und 31 in a munner` which will lielclenr 'from the description l ot' the construct ion first described.

The action is positive throughout and thoroughly reliable, and therentiredevice is Well adapted to moet the requirements of the most severe practical use.

As many. changes could be inside in the above eonstructionand many apparently widely diterent embodiments o this invention could be nisidc'without departing from the scope thereof, it is intended that all.

metter contained in the above description or shown in ,the accompanying drawings siizill be interpreted :1s illustrative and not; in u iiiiiiting scuse. It is also to be understood tlnit the-language used in the follow-.-4 ,ing claims is intended to cover all of the generic'end Specific features of the invention 'nereindeeerihed and all statements of the scope of-jlhi'r. invention, which, :is a matter of language, might he said' to full therebetween. Hoving described our invention what We claimus new und desire to' secure by Letters Patent is: v

1. In n 'device of the nature disclosed, in

combination, a vehicle body, a v ehicle axle,

a spring interposed between said axle and sind hotly and'connected with both, a pair of arms-mounted to swing as said spring is tively thereon in rigid relation a com portion, said cam portions. having along their adjacent surfnces three or more intermcshing projections the sides of which are iii-v elined at ingles of less than 30e with \the 'compressed' or expands und having rcspeoplanes in -which they swing, means holding said czimiportions inoperative relation one to onothdr to permit. free Stringing with 'respeet one to another, and resilient ineens tendine' towirge said com portions together, said several. ports being formed and related to tend to return said arms to :i predeterniined norma relative position from any position into which theyigireimoved in use.'

2. In a. device of the nature disclosed, in combination :i vehicle body, :iV vehicle axle, a spring interposed between said axle and seid hotly und connected. with both, u pair of :nous mounted to swing :is said spring is compressed or expands and formed to converge ut their free ends toward a single plainef .seid arms having respectively thereon i n rigid relation n umn portion, said rain portions being intereini'igeuble and huving on their adjacent surfaces threel or more inter-meshing projeetions thesides of which are inclined at'angies of less than 309 with their planes, means -tions in operative r 6 to permli:` free swin holding sid cam por,`

elation one to anotherng with respect one to another, and. resilient means tending to urge said cam portions together, saldsever'al parts being vformed an related to tend to retuxfn said arms to a, predetermined rnormal relative position from any position into` which -they are moved 1n use.
